Title: Positioning apparatus and method for precision pouring of a liquid from a vessel
Inventor: KEOUGH GRAHAM A
IPC: G05D3/12
Filed: 2000-06-12
Abstract: Apparatus and method accomplishes the precision pouring of a liquid from a vessel (20) to a predetermined position with a controlled rate of flow. Independently controllable horizontal and vertical translation of the vessel (20) is accomplished by using two rotational elements (30, 40) lying in substantially parallel planes, with the rotational axis of the second element (40) passing through the first element (30), and having offset first and second axes of rotation. Independently controlled tilting of the vessel (20) about a third axis of rotation that passes through the second element (40) maintains a desired pour rate and aim point of the pour stream. The apparatus is particularly useful when the vessel (20) and the container (25) that receives the liquid are inside of a sealed chamber (15).

Patent CA-2341830-A1 (CA)
Inventor: DEGNER RICHARD ALAN
IPC: G01V1/104
Filed: 2001-03-22
Abstract: A system for creating seismic exploration shot-holes. A slender shaft is formed into the soil and the lower end of the shaft is underreamed to generate a cavity. An explosive material is positioned within the cavity and is detonated to generate seismic source energy. The slender shot-hole reduces the drilling material excavated and substantially reduces the seismic source energy dissipated upwardly through the shot-hole. The explosive filled cavity can be spherical, conical, hemispherical, or other shapes to maximize the transfer of seismic source energy from the explosive material to the subsurface geologic formations. The invention significantly expedites shot-hole drilling and provides an improved system for coupling the explosive material energy to the geologic formations.

Le cycle de vie (200) de la carte et le gestionnaire de carte englobent les phases suivantes: Pré-production, Finalisation, Initialisation, Sécurisation, Verrouillage et Terminaison. Le cycle de vie (220) d'une application comprend les états suivants: Installé, Selectionnable, Personnalisé, Bloqué, Verrouillé et Effacé. Un registre de carte (250) assure le suive du gestionnaire de carte et des éléments de données d'application. La fonctionnalité d'un domaine de sécurité sur une carte a puce est élargie de manière à rendre possible la délégation de la gestion pour des applications de la carte: chargement, installation et/ou suppression d'une application. Le fournisseur d'une application se voit garantir un contrôle et une gestion plus directs de l'application alors que l'émetteur de la carte conserve un certain droit de regard sur la gestion de cette carte. L'émetteur de la carte autorise les fournisseurs d'applications à apporter à la carte des changements préalablement approuvés. Le chargement par délégation d'une application sur une carte à puce (604) implique dans un premier temps la réception d'un ordre de chargement (500) de la part d'un fournisseur d'application via un dispositif d'acceptation de la carte. Cette ordre contient une indication sur l'application à charger (516) et un motif d'authentification (514) annexé. L'ordre est alors vérifié au moyen de ce motif d'authentification. Une application (564) est ensuite reçue de la part d'un fournisseur d'applications, assortie elle aussi d'un motif d'authentification (562) pour vérification. Enfin, l'application est chargée dans la mémoire de la carte à puce (604).

Title: Bolted joint for rotor disks and method of reducing thermal gradients therein
Inventor: EBERT TODD ALAN
IPC: F16B37/00
Filed: 2001-12-13
Abstract: Rotor disk stress is reduced in a bolted joint (52) for connecting adjacent rotor disks in a gas turbine engine (10). The bolted joint (52) includes a bolt hole (70) formed in the first rotor disk (40) and a tube (82) disposed in the bolt hole (70) such that a channel (84) is defined between the tube (82) and the bolt hole (70). A bolt (66) is disposed in the tube (82) such that a gap (88) is defined between the bolt (66) and the tube (82). The gap (88) thermally insulates the bolt (66) from hot fluid in the channel (84). A first passage (96) provides fluid communication between the channel (84) and a forward cavity, and a second passage (98) provides fluid communication between the channel (84) and an aft cavity. Hot fluid passing through the channel (84) reduces thermal gradients in the first rotor disk (40). The tube (82) thermally shields the bolt (66) from the hot fluid to minimize differential thermal growth.
